To ail vtf1/Omit may concern i Be it known that I, ISABELLA' DE DRAGI'rs, a subject of the Emperor of Austria-Hungary, residing at San Francisco, in the county i of San Francisco and State-of California, have invented new-and useful Improvements in Bank-Note Testers, of .which the following is a specification.

The present invention relates to an' improved' apparatus for testing; the genuineness of bank notes and the like, said apparatus being intended to be used by banks and. other institutions for quickly distinguishing a forged or spurious bank note rom a' genuine one,'also 'to test. signatures fon all kinds of documents, and for all other cases in which it' is desirable to minute y and rapidly examine. identification marks.

The object of the invention isito provide Suche device in which the notes or other documents can be placed in position `:for ins'pection through a lens, and removed therefrom, without the necessity of using-the sense of vision for this purpose, and therefore Without the necessity of moving the eye from its exact position in front of the a lens and at the proper focal distance therefrom.

lbase of convenient size and shape, 'upon which are secured two parallel guide strips 2. On these guide strips are erected standards 3, which are apertured `'to forni. bearings for a shaft 4, which, between the standards, is square in cross-section. T the sides of said shaft are secured, close to the inner `Walls of the standards, frame pieces 6, ex-

tending at right angles to said shaftV and to one another, their inner or opposing sides being formed Withgrooyes to receive the .ends of4 rectangular glass -plates 7, which are Secured against outward movement in said grooves "by caps 8 attached by .screws to the ends of said frame pieces 6.-' The frame pieces'shafn' andglassplates thus form ,a l

frame on Vwhich bank notes or other doeiiinents can be placed 'in an upright or nearly upright position for the purpose of examining the same. A Wire 9 secured a't its ends to said standards, and extending therebetween above the plates and trame pieces, serves to prevent the standards from spreading at the top. shaft Il, preferably at a convenient distance from4 the adjacent standard to'conveniently turn the shaftand plates, is a milled Wheel 11, and, secured on said shaft outside said standard and closely adjacent thereto, is a ratchet' 'Wheel 12 having therein four notches 13, corresponding to the four plates carried by the shatt. Pivoted on the outer side of said standard is a dog 14,having a tooth which is adapted Secured to one end of said` the left hand endkand' to engage any one of said notches 13 and" prevent the Wheel from being turned, and

also having, on the other side ofits pivot from the tooth, a tail 16, so that the pressure of the finger applied to said tail will lift the tooth out of the notch 13 and perrlhe inner or opposing edges of said guide strips 2 are vmit the shaft to be turned.

undercut or mortised, as shown at 17, and therein can slide tenons 18 formed on the extended sides 19 of a carrier 21, which can move on the base l to o-r from ythe shaft 11. Said carrier is slotted, as shown at 22, the sides of said slot being undercut, as shown at 23 in Fig. 2, and in said slot there can slide a rib 24s extending downwardly from a base 25, there being attached to said rib a plate 26, extending into the undercut portions of said sides of the slot. On the base 25 stands a tubular post 27, in which, by a s et screw 28, can be adjusted at any height a stem 29, which at its upper end carries a magnifying lens 30.

The mode of use of the ily be understood from the foregoing description. For testing the genuineness of i1 lens to the proper focus, and the stein 29 is lmoved up or down to adjust it to. its roper height. The post 27 is 'moved to the right or left, if'necessary, t'o bring the lens opposite tolthe exact part of the document whichl v 95 device will readpaper or printing, or in the Signat-ure, can

be clearly seen and ini'mediately detected.

The device is especially Well adapted for examining a large number of bank notes or other documents quickly in succession. For this purpose, the lens is first adjusted to the proper distance and position, and the operator turns intermittently the shaft With the left hand, removing the dog by his finger at the proper time from the ratchet .wheel and, as each glass plate in turn is brought to a nearly vertical position, he places with the right hand one of said bank notes in front of said plate. When the shaft is ,moved through a quarter turn, the bank vnote which has just been examined is automatically discharged onto a pile ofpre viously examined bank notes. By thus turning' .the shaft with the left hand, and feed! ing the bank netejs one after the other with the right hand, a large number of notes can be examined 1n a very short time.

' I claim In an apparatus for examining bank notes and the like, the combination of a base,-

four glass plates extending from said shaft at equal angular intervals,'means for rotat-r ing said shaft, and means for automatically arresting said shaft at angular intervals of a right angle, the points of arrest being related to, the directions of the respective plates that said shaft is arrested in a'position in which one of said platesextendsupwardly and inclined from the lens at a slight angle with the vertical.

'In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
